Purpose

Calculate Hotelling's T² contributions for predictions on a model.

Synopsis

tcon = tconcalc(newx,model)

tcon = tconcalc(pred,model)

tcon = tconcalc(model)

Description

Inputs are the new data newx and the 2-way PCA or regression model for which T² contributions should be calculated model. Alternatively, the prediction structure pred calculated with new data can be used in place of the new data itself or both can be omitted (passing model only) to get T² contributions for the calibration data.
